How to use "append" create a structure for a side-menu in the editor and also is it possible to disable a plugin on selection of another one.

[Question]: 1.) I am trying to create a hamburger sidebar for the full-screen view instead of just the mobile view. But when we have dropped the plugin, on dropping any other plugin it is not getting a proper structure on the body to separate the other content and is overlapping. Is there any way to avoid it. 2.) Also on dropping of hamburger side menu, I want the Menu plugin should be disabled. Is there a way to do so. 3.) I would be very helpful if you help it implement it any other way if possible. For reference: - I have used the menu default plugin and changed a bit to serve my purpose....
